### struct E2kContext

    struct E2kContext;

### e2k_context_new ()

    E2kContext *        e2k_context_new                     (const gchar *uri);

Creates a new E2kContext based at `uri`

`uri` : | OWA uri to connect to
Returns : | the new context

### e2k_context_set_auth ()

Sets the authentication information on `ctx`. This will have the side effect of cancelling any pending requests on `ctx`.

`ctx` : | the context
`username` : | the Windows username (not including domain) of the user
`domain` : | the NT domain, or `NULL` to use the default (if using NTLM)
`authmech` : | the HTTP Authorization type to use; either "Basic" or "NTLM"
`password` : | the user's password

### e2k_context_get ()

    E2kHTTPStatus       e2k_context_get                     (E2kContext *ctx,

Performs a GET on `ctx` for `uri`. If successful (2xx status code), the Content-Type, and response body will be returned. The body is not terminated by a '\0'. If the GET is not successful, `content_type` and `response` will be untouched (even if the error response included a body).

`ctx` : | the context
`op` : | pointer to an E2kOperation to use for cancellation
`uri` : | URI of the object to GET
`content_type` : | if not `NULL`, will contain the Content-Type of the response on return.

As with `e2k_context_get()`, but used when you need the HTML or XML data that would be returned to OWA rather than the raw object data.

`ctx` : | the context
`op` : | pointer to an E2kOperation to use for cancellation
`uri` : | URI of the object to GET

`dest_folder` : | URI of the destination folder
`source_hrefs` : | an array of hrefs to move, relative to `source_folder`
`delete_originals` : | whether or not to delete the original objects
Returns : | the iterator for the results

### e2k_context_transfer_dir ()

Performs a MOVE or COPY (depending on `delete_original`) operation on `ctx` for `source_href`. The folder itself will be moved, renamed, or copied to `dest_href` (which is the name of the new folder itself, not its parent).

`ctx` : | the context
`op` : | pointer to an E2kOperation to use for cancellation
`source_href` : | URI of the source folder
`dest_href` : | URI of the destination folder
`delete_original` : | whether or not to delete the original folder

### e2k_context_subscribe ()

                                                             E2kContextChangeType type,
                                                             gint min_interval,

This subscribes to change notifications of the given `type` on `uri`. `callback` will (eventually) be invoked any time the folder changes in the given way: whenever an object is added to it for `E2K_CONTEXT_OBJECT_ADDED`, whenever an object is deleted (but not moved) from it (or the folder itself is deleted) for `E2K_CONTEXT_OBJECT_REMOVED`, whenever an object is moved in or out of the folder for `E2K_CONTEXT_OBJECT_MOVED`, and whenever any of the above happens, or the folder or one of its items is modified, for `E2K_CONTEXT_OBJECT_CHANGED`. (This means that if you subscribe to both CHANGED and some other notification on the same folder that multiple callbacks may be invoked every time an object is added/removed/moved/etc.)

Notifications can be used *only* to discover changes made by other clients! The code cannot assume that it will receive a notification for every change that it makes to the server, for two reasons:

First, if multiple notifications occur within `min_interval` seconds of each other, the later ones will be suppressed, to avoid excessive traffic between the client and the server as the client tries to sync. Second, if there is a firewall between the client and the server, it is possible that all notifications will be lost.

`ctx` : | the context
`uri` : | the folder URI to subscribe to notifications on
`type` : | the type of notification to subscribe to
`min_interval` : | the minimum interval (in seconds) between notifications.
`callback` : | the callback to call when a notification has been received
`user_data` : | data to pass to `callback`.

### e2k_context_unsubscribe ()

    void                e2k_context_unsubscribe             (E2kContext *ctx,

Unsubscribes to all notifications on `ctx` for `uri`.

`ctx` : | the context
`uri` : | the URI to unsubscribe from
